Professor Ren's discussion of fish eye really reminded me of a GoPro I had from back in the day! The camera had a lens with a tiny focal length (camera was almost a perfect cube), which explains why the field of view was so wide.

When I was reviewing for the midterm, I realized that the upper right picture was shot with 14 mm focal length, which is shorter than 15mm focal length and should imply a wider FOV. But if you look at the upper left corner of the picture shot with 15mm focal length, there is a window on the wall, which is not present in the picture shot with 14mm. Is it related to those straight lines being curved with 15mm focal length? Since 15 mm focal length would curve the straight line, why doesn't 14mm focal length curve those straight lines?
